Hi,<br>
First, I'm not sure I understand why you modified rtkfdk, the
command line options would have allowed you to do all the
modifications I think without changing the code. I'm not going to
debug your piece of code...<br>
Regarding the geometry, this is clearly a difficult step but that's
your job to understand how to translate your geometry parameters to
RTK geometry using the document on the wiki.<br>
Good luck!<br>
Simon<br>

<p class="MsoNormal"><span lang="EN-US">Have you solved your
problem ? If not, my guess would be that you have not
set the origin of your projections correctly. Where does
your calibration assume the location of point (0,0) in
your projections? Since you have very small X projection
offsets, it probably assumes that it's at the center of
the projection so you must set the origin, i.e., the
coordinate of the first pixel, at (0.5*0.254*767,
0.5*0.254*959). If you don't do that, rtkfdk detects a
large offset that it cannot correct for.<o:p></o:p></span></p>
